Ajoene / ˈ ɑː h oʊ. iː n / is an organosulfur compound found in garlic (Allium sativum) extracts. It is a colorless liquid that contains sulfoxide and disulfide functional groups. The name [1] (and pronunciation) is derived from "ajo", the Spanish word for garlic.
Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
Garlic is present in the folklore of many cultures. In Europe, many cultures have used garlic for protection or white magic, perhaps owing to its reputation in folk medicine. [44] Central European folk beliefs considered garlic a powerful ward against demons, werewolves, and vampires. To ward off vampires, garlic could be worn, hung in windows ...
Diallyl disulfide (DADS or 4,5-dithia-1,7-octadiene) is an organosulfur compound derived from garlic and a few other plants in the genus Allium. [3] Along with diallyl trisulfide and diallyl tetrasulfide, it is one of the principal components of the distilled oil of garlic. It is a yellowish liquid which is insoluble in water and has a strong ...
As such only the L-enantiomer is significant biologically. SAC constituent of aged garlic. A number of related compounds are found in garlic, including the disulfide S-"allylmercaptocysteine" (SAMC, HO 2 CCH(NH 2)CH 2 SSCH 2 C=CH 2) and γ-glutamyl-S-allylcysteine" (GSAC). [1] Allylcysteine is of interest for its potential medicinal properties.

Undiluted garlic oil has 900 times the strength of fresh garlic, and 200 times the strength of dehydrated garlic. [6] Ether can also be used to extract garlic oil. [2] A type of garlic oil involves soaking diced or crushed garlic in vegetable oil, but this is not pure garlic oil; rather it is a garlic-infused oil. [2]
The characteristic taste and odor of garlic is due to an oily, slightly yellow organosulfur compound S-Allyl prop-2-ene-1-sulfinothioate, commonly called allicin. Fresh garlic has little odor until it is chopped or crushed. Allicin is produced from alliin (a derivative of the amino acid cysteine) by the enzyme alliinase. [4]
